“An early version of Project Spartan is available in this flight.
It uses our new rendering engine to give greater interoperability
with the modern mobile web, and includes early versions of
Reading View and Reading List,” Microsoft’s Gabe Aul wrote
in a blog post.

Aul added Project Spartan isn’t the default browser in this
preview yet, as it will be available alongside IE11. But Project
Spartan’s Program Manager Kyle Pflug wrote
in a separate blog post that it will eventually become the
only browser included on Windows phones.

Pflug added some tweaks have been applied to the latest Project
Spartan for mobile, including the address bar’s move up top, and
the inclusion of a small actions bar at the bottom.

“We’ve heard your early feedback about the position of the
address bar, and we are looking closely at the design. We
encourage you to try out, see what you think, and continue to
share your feedback with us,” Pflug wrote.

Other updates include new mail and calendar apps, as well as new
phone and messaging apps. It also expanded the types of devices
compatible with this preview.
